Spatial Distribution of the Annual Atmospheric Carbon Dioxide in the Contiguous USA and Their Controlling Factors

Assessment of long tubing in measuring atmospheric trace gases: applications on tall towers

“…[1][2][3] Concentrations of these trace gases along with their spatio-temporal variability at ground level have been well characterized so far. [4][5][6] However, their vertical variations and inuential factors are rarely reported due to the difficulty in obtaining direct observations. Knowing vertical structures and key drivers of these trace gases is important for elucidating their source emission characteristics and roles in regulating climate change and air quality at both regional and global scales.…”
